RIVET OR EYELET SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 229,459, dated June 29,1880.

Application filed May 10, 1880.

To all whom it may concern:

Be it known that we, CLARK M. PLATT and WILLIAM WV. BRADLEY, ofWaterbury, in the county of New Haven and State of Connecticut, haveinvented a new and Improved Rivet or Eyelet Setting Machine; and we dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making part ofthis specification.

This invention is in the nature of an improvement in self-feeding rivetor eyelet setting machines; and the invention consists in a self-feedingrivet-setting machine constructed with a revolving feed-box, with itslower edge serrated, and combined with a ratchetwheel, pawl, andpawl-lever, and a feedingchannel provided with spring-fingers and havinga spring stop-plate at its lower end, in combination with a lever withspring-jaws at its front end to receive the rivets as they are deliveredfrom the feed-channel, and an operating-lever, punch, and die, allarranged and constructed to be operated in the manner hereinafter moreparticularly described.

In the accompanying sheet of drawings, Figure 1 represents a perspectiveview of our machine; Fig. 2, a front view of the feeding mechanism; Fig.3, a section on line 0000, Fig. 2, of the feedbox, ratchet, &c., Fig.4., a longitudinal section of lower part of channel-bar; Fig. 5, asection of spring-holder for rivet; Fig. 6, a crossscction ofchannel-bar in line y 3 Fig. 4; and Fig. 7, a detail view of punch anddie, showing setting of rivet.

Similar letters of reference indicate like parts in the several figures.

The purpose of this invention is a machine to set rivets in shoes and inany other thing that it may be desired to apply them to, the rivetsbeing fed to the machine automatically as it is operated.

To that end our machine is constructed with a base, A, and curved arm B,east therewith. To the front end of the base A is fitted a die, a, andthe front end of the arm B is drilled to receive through it a punch, C.The upper end of this punch is, bya rule-joint, b, fitted to the frontend of an operating-lever, D. This le- (No model.)

ver is fixed to the arm B by a fulcrum-pin, 0, near its front end.

Fitted to the arm B, at or near its base, and by a pivotal bolt, is alever, E, with a spring, (I, connected therewith. The front end of thislever has formed on it a striker, e, and also fixed to this lever, andprojecting from the front of thesame and below the striker e, is aspring catch or holder, F, made with two jaws, E E

To the curved arm B is securely fixed, by bolts or in any desirablemanner, and at an angle pointing to the holderF, a channel-bar, G. Thischannel-bar has formed in its upper surface, from end to end of thesame, a channel, f, and this channel has in section a formeorrespondinginshape to the head of the rivet.

To the upper end of the channelbar G is caster otherwise secured theretoa circular base, H. The face of this plate is countersunk, with a curb,h, cast thereon around a portion of the same, and a curb, g, secured tothe other part of the base.

Accurately fitting \vithinthe curb h, whose innerside forms abearing-surface for the same, is a circular feed-box, J. Centrally castonto this i'eed-box is a bearing, 7c, into which hearing is received aspindle, Z, which passes through the center of the base H, to whichspindle it is held by a nut and screw on the end of the spindle.

The lower edge of the feed-box J is serrated, the teethi being placedobliquely to the edge of the feed-box. The upper surface of the feedboxJ is provided with feed-openings m.

The spindle Z, on which the bearing is of the feed-box J rests, asbefore mentioned, passes through the base H and projects beyond the rearsurface of the base. To this rear projecting end of the spindle l isfixed a ratchet-wheel, K. Engaging into this ratchetwheel K is a pawl,o, fixed to a lever, L, which at one end encircles the projecting partof the spindle I, so as to freely turn thereon, and its other end hasformed upon it a ball, which is received in a socket at the upper end ofan arm, M, the lower end of which arm is connected by a similarball-andsocket joint to the operating-lever D.

To the lower end of the channel-bar G is fitted a stop or spring upsetplate, N. This plate closes substantially the lower end of the channelf,which lower end, as at 'r, is some what larger than the rest of thechannel.

To the lower portion of the channel-bar G, and at or near its lower end,are fitted two spring-fingers, s s. Thesefingers rest on the face of thechannelbar G, one on each side of the channel f and one slightly abovethe other. These spring-fingers are both attached to one and the samespring, S. Engaging with this spring S is the bent end t ofatripping-rod, T, the upper end of this rod being secured to thepawl-lever L.

Now, our rivet-setting machine being constructed substantially as it hasbeen hereinbefore described, it is operated as follows: The feed-box J,through the openings m, is supplied with the rivets or eyelets t, placedtherein without regard to any special arrangement or order. The rear endof the operatinglever D then being moved up and down by a treadle or inany other desirable manner, motion is at once communicated, as thislever is raised, to thepawl-lever L through the arm M, and as this leverL is raisedit causes the pawl 0 to engage in the ratchets of theratchetwheel K, causing this wheel to revolve, carrying with it thespindle l, to which the feedbox J is affixed, giving to this feed-box ani11- termittent rotary motion from left to right, and as this feed-boxin this way turns, the rivets which are placed therein are tumbled aboutwithin the box, finding exit through the serrations on its lower edgeinto the channel of the base H and channel-bar G, with their headsdownward within said channel and their shanks at right angles thereto.When the rivets are within this channel they gravitate toward the lowerend of the channel-barG until they are broughtin contact with thespringfinger s, which holds or checks the descent of the rivet, when, bythe raising of the pawllever L, the bent end t'of the tripping-rod T iswithdrawn from contact with the spring S, and when this is done thespring S, by its retractile force, sends back the point of the finger 8clear of the rivet in the channel f, and permits the rivet then todescend in the channel until it is brought in contact with the end ofthe finger s, which last-named finger is projected across the channel fto catch the rivet by the action of the spring S at the same instantthat the rivet is released by the withdrawal of the finger s, so that asthe operating-lever D continues to be moved up and down the fingers s salternately retain and release the rivet in the channelf by the actionof the spring S and the bent end t of the tripping-rod T, and as therivet is released by the lowermost finger, s, it passes into theenlarged end "1' of the channel f until its head is brought in contactwith the upset plate N, when the stem of the rivet, preponderating,tumbles the rivet over, shank downward and head up, in which position itis received in the holder F, where it remains until, by the action ofthe operating-lever D, the punch O strikes its head, and at the sametime opens the jaws E E of the holder F, permitting the head of therivet to pass through the holder and be forced through the leather orother fabric to which it is to be applied, resting on the die a beneaththe holder F, which die receives the end of the shank of the rivet afterit has passed through the fabric, and upsets or clinches the end of theshank on the wrong side of the fabric, and completes the operation. Asthe punch G descends to produce the riveting, asjust described, theholder F, by reason of the pivoting of the lever E, to which it isattached, descends with the punch, acting thereby as a carrier todeposit the rivet on the fabric, and when the punch is raised by theoperation of the lever D the holder F is restored to its former positionimmediately beneath the upset plate N by the retractile force of thespring (I, where it remains ready for the next rivet, and so on. Theheight to which the lever and bolder are raised is fixed by the strikere, which is brought in contact with the lower end of the front of thearm B. As the feed-box J continues to revolve the rivets are depositedin the channel f, one after the other, until the supply in the box isexhausted.

From the foregoing description it will be seen that the riveting andfeeding of the rivets to be operated on are performed automatically andat the same time by the working of one operating-lever.

The teeth t are placed in a position oblique to the edge of the feed-boxJ at such an angle as will, when the box revolves, present the openingsbetween the teeth parallel with or in continuation of the channel f inthe channelbar G.

Having now described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. A combined rivet setting and feeding device with a circular feed-boxprovided with oblique serrations entirely around its lower edge andconstructed to revolve intermittingly in one direction, substantially asand for the purpose described.

2. In a combined rivet setting and feeding device, a pawl-carryinglever, in combination with an arm fitted to said lever and to theoperating-lever of the device by means of ballto alternately retain andrelease the rivets within the channel-bar, substantially as and for thepurpose described.
